RA de Groot N.N.;
RL Submitted (OCT-2016) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Catalyzes the irreversible NADPH-dependent deamination of GMP
CC to IMP. It functions in the conversion of nucleobase, nucleoside and
CC nucleotide derivatives of G to A nucleotides, and in maintaining the
CC intracellular balance of A and G nucleotides.
CC {ECO:0000256|ARBA:ARBA00037691, ECO:0000256|HAMAP-Rule:MF_01511}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=IMP + NADP(+) + NH4(+) = GMP + 2 H(+) + NADPH;
CC Xref=Rhea:RHEA:17185, ChEBI:CHEBI:15378, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:57783, ChEBI:CHEBI:58053, ChEBI:CHEBI:58115,
CC ChEBI:CHEBI:58349; EC=1.7.1.7;
CC Evidence={ECO:0000256|ARBA:ARBA00000930, ECO:0000256|HAMAP-
CC Rule:MF_01511};
CC -!- SIMILARITY: Belongs to the IMPDH/GMPR family. GuaC type 2 subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_01511}.
